I have a dataset 'A' containing matched cases and controls. The matched cases and controls exist as a single line observation. I have another dataset 'B' where I've identified certain controls from within A that I dont want to include in my study anymore. How can I drop the matched pair lines from A using the observations from B? (using SAS 9.4)

Please provide examples of the input data sets, preferably as datastep code and what the desired output for those input sets would be.
